Virtual Stores in Korea – imagine a store that isn’t a store. No shelves just pictures of shelves with products and QR codes. Number of cash register clerks required = 0.

This video for an automated grocery store – no cash registers, no cash register clerks, reduced shrinkage, no benefits to pay all these employees that the store no longer has, the store doesn’t have to buy shopping carts, reduced retail square footage purchased to supply your customers and happier customers that have done less work to buy the same things they were getting before.
